OPERATION AND ADJUSTMENTS The following precautions are from the NEMA Standards Publication ICS (English version prevails): Regardless of the care exercised in the design and manufacture of equipment or in the selection and ratings of components, there are hazards that can be encountered if such equipment is improperly operated. It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe operation. Always use the manufacturer s instructions as a guide for functional adjustments. Personnel who have access to these adjustments should be familiar with the equipment manufacturer s instructions and the machinery used with the electrical equipment. Only those operational adjustments actually required by the operator should be accessible to the operator. Access to other controls should be restricted to prevent unauthorized changes in operating characteristics. 3 Overview The model 5505 RTD input module adds four RTD inputs to the 5000 input/output system. Up to sixteen Model 5505 modules may be connected to the I/O bus, for a total of 64 RTD inputs per bus. These RTD inputs are used with 3 or 4 wire 100 ohm platinum RTDs that conform to the ohms/ohm/ C calibration standard based on ASTM E 1137/E 1137M-04. Resistance from 0 to 500 ohms and RTDs from 200ºC to 800ºC can be measured.

7 5505 RTD Input Module 7 The 5505 module scales and linearizes each RTD input and returns the individual data in ohms, C, F or K as a 32 bit floating point number. The 5505 module provides 4mA excitation current with a low duty cycle. The high excitation current along with the low duty cycle results in high accuracy while minimizing self-heating. The 5505 module can detect whether a 3 or 4 wire RTD has been wired and will excite and monitor the RTD accordingly. The 5505 module uses a 24-bit delta sigma analog to digital (A/D) converter. A single chip microcontroller with integral watchdog timer operates the A/D, linearizes and scales the output data and communicates over the I/O bus. Inputs have transient protection and are optically isolated from the main logic power. F igu re 1 : RTD In pu t M odu le

8 8 SCADAPack E 5505 RTD Input Hardware Manual 4 Installation The installation of the 5505 module requires mounting the module on the 7.5mm by 35mm DIN rail and connecting the module to the system I/O Bus. Refer to the System Configuration Guide, at the beginning of this manual, for complete information on system layout, I/O Bus cable routing and module installation. Field Wiring Controller, modem and I/O modules use screw termination style connectors for termination of field wiring. They accommodate solid or stranded wires from 22 to 12 AWG. The connectors are removable. This allows module replacement without disturbing the field wiring. Leave enough slack in the wiring for the connector to be removed. Remove power before servicing unit. To remove the connector: Pull the connector upward from the board. Apply even pressure to both ends of the connector. To install the connector: Line up the pins on the module with the holes in the connector. Push the connector onto the pins. Apply even pressure to both ends on the connector. The 5505 module provides four RTD inputs for use with 3 or 4-wire RTDs. Figure 2: Typical 5505 RTD Field Wiring shows how to wire these RTDs. When using 4 wire RTDs, the four wires are connected to the Sense + (S+), Sense (S ), Excitation Current + (I+) and Excitation Current (I ) terminals. The I+ and I terminals supply the excitation current to the RTD. The S+ and S terminals return the sensed voltage to the 5505 module. 4 wire measurement techniques are the more accurate and consume the least amount of power. Although the circuitry and measurement technique can compensate for wiring resistance, the user should minimize the lead resistance as much as possible. When using 3 wire RTDs, three wires are connected to the Excitation/Sense + (I/S+), Sense (S ) and Excitation Current (I ) terminals. The I/S+ and I terminals supply the excitation current to the RTD. The S+ and S terminals return the sensed voltage to the 5505 module. The Excitation Current + (I+) terminal is not used. The wiring resistance is monitored and compensated. In 3 wire installations the 3 wires are of the same length and type for this compensation to be accurately performed. A DC supply powers the isolated RTD input circuits. A 5000 power supply or SCADAPack controller normally sources this voltage. A range of voltages can be tolerated. Refer to the specifications for details. In systems where multiple 5000 modules and other devices are connected to the DC power supply, it is possible for noise to be coupled into the DC power supply. For these reasons it is recommended that the negative side of the DC supply be connected to the panel or chassis ground. This connection can be made on the 5000 power supply, SCADAPack terminal blocks or as part of the panel wiring.

The free internal volume of the enclosure must be dimensioned in order to keep the temperature rating. A T4 rating is acceptable.

10 10 SCADAPack E 5505 RTD Input Hardware Manual 5 DIP Switch Settings Address Selection 5000 Series I/O module types may be combined in any manner to the maximum supported by the controller used. Each type of I/O module, connected to the I/O bus, has a unique I/O module address. Different types of I/O modules may have the same module address. The address range supported by the SCADAPack controller module may restrict the I/O module address range. Refer to the controller manual for the maximum address supported. Each analog input module has a unique set of channels. The four address switches labeled 1, 2, 4 and 8 set the module address. To set the address: Open the four switches by sliding the actuator to the left side of the switch. Slide actuators to the right such that they total the desired address. Figure 3: 5505 Analog Input Module Address Switches shows the switch setting for each of the 16 module addresses. Figure 3: 5505 Analog Input Module Address Switches 5503 Emulation Mode Switch 5503 Emulation mode is not supported for SCADAPack E controllers. The Emulation switch is set to the left position.

11 5505 RTD Input Module 11 6 Operation and Maintenance F igu re 4 : Em u lation Sw itch. The 5505 RTD module is configured for use using the SCADAPack E Configurator SCADAPack I/O property page. Each input is individually configurable for resistance measurement or RTD temperature measurement Each RTD input is configurable to return the measured temperature in degrees Celsius, Kelvin, or Fahrenheit. Inputs have a common configurable filter rate that can be used to dampen process variations or noise. Data is returned as an IEEE 32 bit, single precision floating point number that requires no additional scaling. Data Format The 5505 module returns RTD resistance and temperature data. The returned data is in floating point format. You will need to use the g30v1 32bit Analog In object type for the data. The RTD data is returned via one of the following methods: The following table shows the data output for o C, o F, o K, and Ohms for the 5505 RTD module.

The Analog Input Point Attributes dialog, selected from the SCADAPack E Configurator SCADAPack I/O property page, displays the point quality flags for the RTD status of the analog input points. The following status conditions are reported: When the 5505 RTD module detects an Open condition on the RTD channel or Power Input Off condition, the point Over-range quality flag is set. The point value reported in SCADA protocols is set to e+038. When the 5505 RTD module detects a low Out-of-Range condition on the RTD channel, the point Under-range quality flag is set. The point value reported in SCADA protocols is set to e+038. When the 5505 RTD module indicates a high Out-of-range condition on the RTD channel, the point Over-range point quality flag is set. The point value reported in SCADA protocols is set to e+038. When the RTD channel returns to a valid reading, the analog point quality flags are cleared.
